ROCKWELL L. GALLUP, OF CHICAGO, ILLINOIS, ASSIGNOR, BY MESNE ASSIGNMENTS, TO NICHOLAS GLAB, OF DUBUQUE, IOWA.

BOTTLE-WASHING MACHINE.

To all whom it may concern:

Be it known that I, ROCKWELL L. GAL- LUP, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Bottleashing Machines, of which the following is a specification.

This invention relates to bottle washing machines and aims particularly to provide a machine of this character which will effectually and thoroughly wash and cleanse both the interior and exterior of bottles of various kinds such as beer bottles, milk bottles, etc.

One of the objects of the present inven tion is the provision of a bottle washing machine which shall be compact and simple in construction, and in which the bottles will be subjected to a number of washing and rinsing operations. In order to position the bottles successively in cooperative relation to the washing and rinsing devices and at the same time to confine the size of the machine so that it will take up a minimum amount of floor space, I have constructed the bottle carrying mechanism so that it travels in a substantially circular orbit which is flattened at the top adjacent to the bottle washing and rinsing devices in order that said devices may be inserted into the bottles simultaneously and in parallel relation.

Another object of this invention is the provision of novel and improved mechanism for operating or revolving the bottle washing spindles, the mechanism being so de signed that each spindle is operated independently of its companion spindles and the spindles and operating mechanisms therefor being so mounted that they will run with the least friction and minimum amount of noise.

Still another object is the provision of mechanism for holding bottles of various sizes against rotation with the washing spindles, which mechanism is adapted without manual adjustment to grasp and hold quarts, pints, or splits against rotation with the washing spindles. The holding mechanism is constructed to engage with the bottles before they'are elevated andto yield as the bottles are raised without releasing its grasp on the bottles or permitting them to revolve with the spindles.

Patented Apr. 21, 1914. Serial No. 602,834.

Still another object is the provision of improved brushing mechanism for brushing and cleansing the bottoms and sides of the bottles, and to so mount the brushing mechanism that it can be moved longitudinally of the bottles to brush the same throughout their length without interfering with the rotation of the brush.

A further object is the provision of adjusting devices by means of which the normal position of the brush may be adjusted so that the brush will clean the bottoms of various sized bottles.

In the accompanying drawings I have illustrated one preferred embodiment of my invention, but it will be obvious from inspection thereof, in connection with the following description to which reference is made for a complete understanding of the details of this specific embodiment, that my invention is capable of being carried out in various other forms than that shown and described, and that its scope is not to be restricted to the particular embodiment which has been selected for purposes of illustration in this application.

Referring to the drawingsFigure 1 is an end elevation of a bottle washing machine embodying my invention. Fig. 2 is a plan view thereof. Fig. 3 is a vertical sectional view on the line 33 of Figs. 1 and 2. Fig. 4 is a detail plan view of the motor casing showing the arrangement of the washing and rinsing spindles and the spindle driving motors. Fig. 5 is a sectional elevation on the line 55 of Fig. 4. Fig. 6 is a detail perspective of a section of the motor casing and one of the fluid motors mounted therein. Fig. 7 is a perspective of the propelling frame for the bottle carrying members. Fig. 8 is a detail of one of the bottle carrying members showing its manner of mounting and method of connection with the propelling frame. Fig. 9 is a sectional elevation on the line 99 of Figs. 1 and 2. Fig. 10 is an elevation of the brush operating mechanism looking toward the right in Fig. 9. Fig. 11 is a vertical section through a bottle showing the washing spindle and the bottle holder in operative position; and Fig. 12 is a detail view showing the contour of the cam for "actuating the bottle holding mechanism and of the cam for reciprocating the bottle scrubbing brush.

Referring to the drawings in which like reference characters indicate corresponding parts in the several fi ures, 15 indicates the base or bed of the mac iine presenting a substantially flat top to which is fixedly secured by bolts 16 or otherwise, a vertically disposed frame 17. The ends of this frame are circular in shape, as clearly shown in Fig. 1, and each end-piece is provided on its inner face with a groove or channel 18 forming a track or guideway around the frame which is substantially circular in shape except at the top of the frame where the track is flattened by forming a portion of the length of the groove in a horizontal plane for a purpose to be later described.

A propelling frame of cylindrical shape is composed of circular end members 19 rigidly secured together by rods 20, as shown in Fig. 7. This frame is supported concentrically of the stationary track frame upon supporting rollers 21 journaled in standards 22 carried upon the base of the machine. Said rollers, four in number, are provided with peripheral grooves in which the end members 19 of the propelling frame are adapted to travel, the grooved supporting rollers permitting rotation of the propelling frame between the end members of the stationary frame and at the same time preventing longitudinal displacement of the propelling frame by reason of the peripheral grooves. By mounting the propelling frame upon the supporting rollers, as above indicated, I am enabled to eliminate from the in terior of the frame a concentrically disposed bearing shaft and also to obviate the employment of radial spokes at the end of the frame, thereby leaving the interior of the frame free for the arrangement and assemblage of the bottle washing appliances and the operating and actuating mechanisms. The circular end members 19 are provided with a series of spaced radially disposed slots or grooves 23 which open interiorly of the frame, as shown in Figs. 1 and 7.

The open-ended grooves or slots 23 are adapted for sliding engagement with bottle carrying members designated generally as 24. From inspection of Fig. 8 it will be apparent that each of these members comprises a body portion equipped with a plurality of laterally extending open-mouthed sockets 25, each constructed to receive and support the neck of a bottle disposed in inverted position in the socket. Each end of the body portion 24 is contracted to form a bearing or trunnion 26, upon which is mounted a roller 27 of proper size to fit loosely in the radial slots 23 of the propelling frame. The ends of the bearings or trunnions 26 are squared at 28 to receive the centrally arranged squared aperture 29 of a supporting arm 30 provided with laterally projecting pintles 31 upon which are mounted the bearing rollers 32. These rollers are retained in position on the pintles by bolts and washers 33 and 34 or other preferred fastening means, and the supporting arm is secured upon the squared end 28 by a similar bolt and washer 35 and 36, all as plainly shown in Fig. 8. The bottle carrying members are assembled with the bearing rollers 32 arranged to travel in the tracks or guideways 18, the bearing rollers being mounted near the ends of the supporting arms 30 for the purpose of maintaining the mouths of the bottle receiving sockets at all times substantially parallel with the surface of that particular portion of the track over which the rollers 32 are traveling. It will be evident that upon rotation of the propelling frame the bottle carrying members will be propelled in succession around the circular track 18, the sliding engagement between the bottle carrying members and the propelling frame enabling the members to move radially of said frame and follow along the flattened portion of the track as they are brought to the top of the machine.

The propelling frame is intermittently rotated step by step by means of an oscillatory lever 37 (Fig. 1) carried upon a stub-shaft 38 suitably mounted in bearings on the frame of the machine, and equipped at its lower end with a pawl 39 which is adapted to successively engage the inner edges of the radial slots 23, to rotate the propelling frame a distance equal to the spacing of the slots at each actuation of the lever 37. The upper end of lever 37 has attached thereto at 40 a link 41 which is connected with a strap 42 surrounding an eccentric 43 fixed upon the shaft 44 which extends longitudinally of the machine within the frame and is equipped at its opposite end with a gear 45 adapted to mesh with and be driven by a worm 46 secured upon a transversely extending shaft 47 (Figs. 1 and A spurgear 48 is fixed upon said shaft 47 in position to mesh with and be driven by a pinion 49 secured upon the driving shaft 50 of a suitable motor 51. It will be evident that operation of the motor will, through the gears 49 and 4S, revolve the transverse shaft 47 which, in turn, through the worm and gear connection 46 and 45 will rotate the shaft 44 at a reduced speed so that the lever 37 will be intermittently actuated to impart a step by step rotary movement to the propelling frame whereby the bottle carry ing members are propelled around the track 18.

- Centrally of the frame and at each end thereof there are arranged vertically disposed guideways 52 in which guide blocks 53 (Figs. 1 and 4) are adapted to reciprocate in a vertical plane. These guide blocks are rigidly secured to a motor casing designated generally as 54, and carried by the easing is a plurality of series of washing spindles 55, which project upwardly into guides 57 (Fig. 3) carried by a plate 58 rigidly secured at each end to the stationary frame 17 and disposed directly beneath the flat portion of the track 18. When the motor casing is elevated the spindles carried thereby will be projected above the track and into the bottles held by the bottle carrying members in inverted position in alinement with said spindles. In order to raise and lower the spindles at regular predetermined intervals I have mounted in the frame of the machine a longitudinally extending shaft 57 carrying a gear 59 adapted to be rotated by a worm 60 secured upon the transverse shaft 47. A rock-shaft 61 is suitably mounted in the main frame of the machine in parallel relation with the shaft 57 and upon each end of said rock-shaft there are secured arms 62, 63, which are connected by means of links 64, 65 with the motor casing carrying blocks 53. The arm 62 has mounted thereon intermediate its length a boss 66 carrying a roller 67 (Figs. 1 and 2) which is adapted to travel in a cam groove provided in the lateral face of a cam 68 rigidly secured upon the outer end of the shaft 57. It will be evident that rotation of said shaft 57 and the cam 68 will rock the shaft 61 to alternately raise and lower the motor casing and the washing and rinsing spindles carried thereby. For the purpose of balancing the motor casing and relieving the operating mechanism of the weight of said casing I have provided a pair of counter-balance weights 69 which are suspended from flexible cords or chains 7 O trained over pulleys 71 and connected at their other ends to the motor casing, as shown in Fig. 1. These weights substantially balance the casing and mechanism connected therewith so that the washing and rinsing spindles may be raised and lowered by a minimum expenditure of energy.

Referring now more particularly to Figs. 4, 5 and 6, it will be apparent that the motor casing 54 is preferably cast to provide integral side and end walls and a bottom provided with a longitudinally extending opening 7 2 to permit the escape of exhaust motive fluid from the casing. Upon each side of this opening the bottom is formed with a longitudinallyextending channel or passage way 73 which opens at intervals into the casing through studs 74 each threaded to receive a nipple 75 tapered at its upper end tov provide a cone-bearing for the reception of the end of a motor shaft 76. The motor shaft is hollow to communicate with the passageway 7 3'through the nipple 75 and is provided with a shoulder 77 above the radially disposed blades or pockets 78 against which an adjustable thrust-bearing 79 is adapted to be threaded to take up the wear between the lower end of the motor shaft and the cone-bearing nipple 75 and insure a tight fit at this point to prevent the escape of liquid between the bearing and end of the shaft and also to prevent noise during the running of the motor. The adjustable thrust-bearing 79 is threaded through the top 80 of the motor casing which is re tained in position by screws, bolts or other fastening means, and a lock-nut 81 is preferably provided to retain the thrust-bearing in adjusted position. The upper end of the motor shaft projecting above the thrustbearing 79 is threaded to receive the socketed lower end of the washing spindle 55. Two series of individual motors, such as above described, are shown as arranged in the motor casing, although it will be obvious that the number of series may be increased or diminished in accordance with a greater or less number of washing spindles required in any particular machine. In order that the spindles may be located close enough together to correspond to the spacing of the bottle receiving sockets on the bottle carrying members without unduly reducing the size of the individual motors, I have arranged the alternate motors in each series in staggered relation, 2'. 0., the adjacent motors are elevated or lowered relatively to their neighbors so that the motors in each series are disposed in two horizontal planes, thus enabling the adjacent motors to overlap, as shown in Figs. 4 and 5. Motive fluid for actuating the individual motors is supplied through nozzles 82 projecting laterally from a fluid compartment 83 disposed centrally of the motor casing, motive fluid being supplied to the compartment through a hose or pipe 84 by mechanism to be later described. In order that the discharge motive fluid from the upper planes of motors may not interfere with the operation of the lower planes of motors, I have provided partitions 85 disposed between the upper and lower planes of motors, said partitions being preferably inclined downwardly and outwardly and provided near their edges with perforations or openings 86 through which the discharge motive fluid may discharge outside the perimeter of the lower motors to the bottom of the motor casing, from whence it escapes through the elongated opening 7 2. I have shown in the present instance two rows of washing spindles 55, each of which is provided at its upper end witha brush 87, as shown in Fig. 11, adapted to enter and brush the interior of the bottles, ,and for the purpose of insuring the cleansing of the interior of the bottles each of the washing spindles is provided with a bore, terminating in lateral perforations 88 through which water is injected into the interior of the bottle, said water, either hot or cold, being supplied to the spindles preferably from the chambers or passageways 73 through the motor shaft, as previously explained. The motor casing is also provided at one side with a passageway 89 provided at intervals with threaded apertures 90 into which the hollow rinsing spindles 91 are adapted to be threaded. A similar passageway 92 is provided in the top ofthe casting forming the motive fluid chamber 83, and similar rinsing spindles 93 are threaded into apertures through the upper walls of the passageway 92. ater is simultaneously supplied to passageways 73, 89 and 92 from a branched pipe 94 which may be connected with any suitable source of water supply, hot or cold, and under suflicient pressure to inject the water into the interior of the bottles through the washing and rinsing spindles. While I have shown both the washing and rinsing spindles as connected with the same source of water supply it will be apparent that the various rows of spindles may be connected with individual sources of water supply of various temperatures and under varying pressures if preferred. The water which is supplied to the washing and rinsing spindles after being injected into the bottles drops back to the bottom of the machine where it is collected in a tank 95 preferably covered with a screen 96 and provided with a suitable overflow pipe 97. The discharged motive fluid which escapes through the opening 72 from the motor casing is also collected in the tank or receptacle 95, from whence it is led to a second closed receptacle 98 through a suitable conduit 99. A rotary pump 100 (Figs. 1 and 3) directly connected with the motor 51 is arranged to draw water from the receptacle 9S and force it through the hose or pipe 84: to the motive fluid chamber 83 located in the motor casing, as previously described. Thus, I am enabled to save the water which has been used for washing purposes and utilize it for driving the spindle actuating motors. It will be evident, however, that instead of employing water for driving the motors, I may, with equal efliciency, substitute compressed air or any other suitable medium adapted for driving fluid actuated. motors.

In order to thoroughly clean the interior of the bottles, and particularly the bottom thereof, it is necessary to insert the washing spindles and brushes into the bottles far enough to permit the brushes to act upon the bottoms of the bottles, therefore the washing spindles are elevated at each raising of the motor casing sufficiently to bring the ends of the washing spindles into engagement with the bottom of the inverted bottles to lift the bottles slightly out of their sockets, as shown in Fig. 11. This machine is constructed and intended for washing and cleaning bottles of various sizes such as quarts, pints and splits, and it will be evident that if the spindles are elevated sufliciently to lift quart bottles out of their sockets the same extent of movement of the spindles will lift pints and splits a greater distance out of the bottle receiving sockets. The spindles, as has previously been explained, are continuously and rapidly revolved by the individual motors, and in order to insure the proper brushing and cleaning of the interior of the bottles by the spindles and brushes it is necessary to prevent rotation of the bottles with the spindles when they are elevated out of their sockets. For the purpose of holding the bottles against rotation I have provided bottle holding mechanism which is adapted to be brought into engagement with the bottles, either quarts, pints or splits, before said bottles are elevated by the spindles out of their sockets, and the holding mechanism is designed to grasp the bottles and prevent rotation thereof with the spindles but at the same time to yield upwardly to permit the spindles to be elevated to the maximum height at each reciprocation of the motor chest. The bottle holding mechanism comprises a cross-head 101 extending longitudinally of the machine and adapted to be guided in its vertical reciprocatory movement by guide posts 102 mounted upon the hood 103 secured to the main frame of the machine, as shown in Fig. 3. The crosshead is preferably forked, as shown in Fig. 2, and each branch is provided with a series of square sockets 104i spaced apart and adapted to receive and guide square bars or rods 105 slidingly mounted in said sockets. Each of said square bars or rods carries on its lower end a holding head 106 provided with diverging holding fingers adapted to engage the bottoms of the bottles, as shown in Fig. 11. The holding members are shown in Fig. 3 in their elevated position, but as the cross-head 101 is lowered it will be evident that the bars and holding heads will be lowered therewith until the holding fingers are brought into engagement with the bottoms of the inverted bottles. The downward movement of the holding members will thereupon be arrested but the crosshead will be lowered by its actuating mechanism to the limit of its movement at each actuation, the relative movement between the cross-head and the holding members being permitted by reason of the sliding ongagement between the cross-head and said members. As best shown in Figs. 1 and 3, the cross-head is reciprocated upon the guide posts 102 by means of arms 107 fixedly secured upon each end of a rock-shaft 10S suitably mounted in the frame of the machine, the free ends of said arms being connected with either end of the crosshead by suitable links 109. The rock-shaft 108 is rocked to raise and lower the cross-head by means of a cam 110 (Fig. 12) fixedly secured upon the shaft 44: and provided with a track upon its lateral face. A link 111 is provided at its lower end with an elongated slot 112 disposed around the shaft 44 and said link has mounted upon one side thereof and in position to travel in the track of the cam 110, a roller or boss 113 by means of which the link is reciprocated in a vertical plane upon rotation of the cam 110. As best shown in Fig. 1 the upper end of the link 111 is pivotally connected with the outer end of an arm 114 rigidlysecured upon the shaft 108 whereby longitudinal reciprocation of the link 111 will rock said shaft 108 and through the arms 107 and links 109 reciprocate the cross-head 101, as above indicated. A counter-weight 101 serves to counter-balance the weight of the crosshead. The reciprocation of the cross-head 101 is so timed that the cross-head arrives at the lower limit of its movement so as to insure engagement of the bottom of the bottles by the holding fingers just prior to the elevation of the bottles by the washing spindles. This engagement of. the exterior of the bottles by holding heads prior to the elevation of the bottles by the spindles insures the centering of the spindles in the bottles and also absolutely prevents rotation of the bottles with the spindles regardless of the size of the bottles and without adjustment of either the spindles or holding mechanism. -By the employment of this novel bottle holding mechanism, quarts, pints and splits may all be washed miscellaneously and simultaneously without sorting the bottles and washing each size separately. It will be evident that if bottles of various sizes are disposed in the sockets of a single bottle carrying member as the cross-head 101 is lowered all of the bottles will be engaged by the holding fingers before the head reaches the lower limit of its movement. In other words, the quarts will first be engaged by the downwardly moving bottle holding heads, and further downward movement of these heads will be arrested. The pints will next be engaged by the holding heads lowered upon them, and lastly the splits will be engaged by the holding heads lowered into engagement with them, but in every instance all of the bottles, quarts, pints and splits will be engaged by the bottle holding heads before the washing spindles are elevated sufliciently to lift the bottles out of their sockets. All of the washing spindles are elevated to the same height and obviously will carry the bottoms of various sized bottles to the same level or horizontal plane, thereby lifting the smaller bottles entirely out of their sockets while the larger sized bottles will be lifted only slightly from their sockets. In any event the bottles are all held against rotation during their raising and lowering movements by the slidingly mounted bottle holding devices, and no adjustment of either the bottle holding devices or the washing spindles is required to enable the machine to wash bottles of various sizes. Upon withdrawal of the washing spindles from the bottles the cross head is elevated to withdraw the bottle holding heads from engagement with the inverted bottles whereupon the propelling frame is actuated to move the bottles one step along the track.

For the purpose of scrubbing the exterior of the bottles to remove the labels, dirt, and other foreign matter adhering to the sides and bottoms of the bottles, I have provided novel brushing and scrubbing mechanism which will now be described.

Referring particularly to Figs. 1, 3, 9 and 10, it will be apparent that guideways 115 and 116 are cast integrally with and project upwardly from the hood 103 which is bolted to the top of the stationary frame 17, as previously indicated, and bearing blocks 117 and 118 are mounted to reciprocate vertically in said guides. Depending brackets 119 and 120 are preferably constructed integrally with said bearing blocks 117 and 118, respectively, the lower ends of said brackets forming bearings in which is mounted a shaft 121 provided with radially extending bristles 122 forming a cylindrically shaped brush, as shown in Fig. 9. A collar 123 secured to said shaft by a set-screw 124 prevents longitudinal movement of said shaft in one direction, and a gear 125 secured upon said shaft 121 prevents longitudinal movement of said brush in the other direction, said collar and gear serving to maintain said brush in position in its bearings. A horizontally disposed shaft 126 is j ournaled near each end in the bearing blocks 117 and 118 and is prevented from longitudinal movement relatively thereto in one direction by a collar 127 secured to said shaft by a setscrew 128. A gear 129 secured to said shaft in position to mesh with and drive the gear 125 prevents longitudinal movement of shaft 126 in the opposite direction. The guide 115 is provided with laterally extending vertically disposed bearings 130 and 131 in which is rotatably mounted a vertical shaft 132 provided between said bearings with a worm 133. As best shown in Fig. 3, the lower end of the shaft 132 is guided in a bearing 134, and an inclined section 135 connects said shaft by two universal joints 136 and 137, with a vertical portion 138 mounted in a suitable bearing on the frame of the machine and provided at its lower end with a bevel-gear 139 adapted to mesh with and be driven by a bevel-gear 140 secured upon the transverse shaft 47. A gear 141 mounted upon the shaft 126 is adapted to mesh with and be driven by the worm 133. From the above description it will be evident that rotation will be imparted to the scrubbing brush 131, 122 through gears 125, 129, shaft 126, gear 141, worm 133, the flexible shaft 132, 135 and 138, from the transverse shaft 47 through the bevel-gears 139 and 140. In its normal position the brush is disposed adjacent to and in contact with the bottoms of the bottles so that the bottoms will be brushed as they are moved along beneath the brush. For the purpose of cleaning and scrubbing the sides of the bottles the brush is lowered between the two rows of bottles shown at the right of the horizontal portion of the track in Fig. 1 The raising and low ering of the brush is effected by a cam 142 (Fig. 12) rigidly mounted upon the shaft 44 and adapted to reciprocate a link 143 slidingly connected with said shaft 44 and provided with a laterally projecting roller, or boss 144 which travels in the groove of said cam. The upper end of link 143 is pivotally connected with an arm 145 fixed upon a rock-shaft 146 mounted in suitable bearings on the stationary frame of the machine. Upon each end of the shaft 146 are secured adjustable arms 147, the outer ends of said arms being connected with vertically disposed links 148 attached at their upper ends to the shaft 126, as shown in Figs. 1 and 9. Vertical reciprocation of the link 143 by the cam 142 will oscillate the shaft 146 to raise and lower the scrubbing brush carried by the bearing blocks 117 and 118. From inspection of Fig. 10 it will be evident that during the raising and lowering movements of the brush the gear 141 will travel up and down the worm 133 remaining in mesh therewith, notwithstanding the fact that said worm and gear are continuously revolving. The arms 147 comprise a portion fixedly secured to the rockshaft 146 and an outer portion 149 telescopically engaging with the portion fixed on the shaft, the portion 149 being adjustable longitudinally of the other portion by reason of a slot 150 therein through which a thumb-screw 151 is passed to clamp the sections of the arm together in adjusted position. The mechanism is so designed that when the brush has reached the lowest limit of its movement the arms 147 are in substantially horizontal position. It will be evident that by adjusting the lengths of the arms 147 the heights to which the brush will be raised may be varied. This adjustment of the arms is provided in order that the height of the brush when in elevated position may be varied in accordance with the size of the bottles to be washed, so that the brush will normally be disposed in contact with the bottom of the bottles as they pass beneath it to brush and scrub the same. When the brush is lowered it will be evident that it will scrub one-half of the periphery of the two rows of bottles between which it is introduced, and when the bottles are moved to the right one step, viewing Fig. 1, and the brush is again lowered the other half of the bottles which have previously been scrubbed will be acted upon and cleaned by the revolving brush.

The operation of the machine briefly is as follows: The bottles are positioned in the bottle receiving sockets atthe left of the machine, viewing Fig. 1. As the propelling frame is moved forward step by step by the oscillating lever 37 the bottles are first positioned Over the washing and brushing spindles located at the left in Fig. 1. The propelling frame is locked to maintain the bot tles in alinement with the spindles by a spring-pressed lock, which consists of a yieldingly mounted roller 152 which is normally urged by an expansion spring 153 into locking engagement with the open end of an adjacent radial slot 23. The washing spindles which are constantly rotated by the individual motors actuated by the motive fluid supplied from the pump 100, are elevated to introduce their upper brushing ends into the bottles. Prior to the introduction of the brushing spindles into the bottles, however, the bottle holding heads 106 are lowered into engagement with the bottoms of the bottles to prevent the same from rotating with the spindles, and as the bottles are lifted out of their sockets by the spindles, the holding heads yield upwardly relatively to the supporting crosshead by reason of the sliding engagement between the bars or rods 105 and the sockets in which they are mounted. Upon withdrawal of the washing spindles the bottles are moved forward one step to bring them over the first set of rinsing spindles which, upon the next. raising movement of the motor casing, are introduced into the bottles to inject a spray of water over the interior thereof. The rinsing spindles, as has been previously indicated, are fixedly mounted on the motor casing and therefore do not revolve. The rinsing spindles furthermore, are shorter than the washing spindles and are not inserted into the bottles far enough to lift the bottles from their sockets. The bottles are next subjected to the action of the second set of washing spindles and subsequently to the action of the last set of rinsing spindles, thus it will be seen that each bottle is first brushed, then rinsed, then brushed again, and finally rinsed a second time, each of the brushing and rinsing actions being carried out with water at any desired temperature. \Vhen the bottles reach the position over the second set of washing spindles the scrubbing brush is lowered and raised prior to engagement of the bottoms of the bottles by the washing spindles, to brush one half of the circumference of the bottles. As the bottles are moved to position over the final rinsing spindles their bottoms are scrubbed by the revolving brush which is at that time in its uppermost position, the height of the brush at this time being determined by the adjustment of the arms 147, as previously described. When the bottles are positioned over the last set of rinsing spindles the scrubbing brush is again lowered to brush the half of the bottles which was not reached by the previous action of the brush. After the bottles have passed through the successive washing, rinsing and scrubbing opera tions they may be removed from the machine by hand or by any preferred automatic mechanism.

From the above description it is believed that the construction, operation, and many advantages of my present invention will be understood and it should now be obvious that my invention is capable of being carried out in mechanical embodiments diflering widely in structure from that shown in the present application.

I claim:

1. In a bottle washing machine, the combination of a plurality of bottle carrying members, a stationary frame having a track along which the bottle carrying members travel, and a cylindrical propelling frame rotatably mounted upon rollers disposed beneath the same, said frame being provided with radially disposed slots loosely engaging bottle carrying members to move the bottle-carrying members along the track, and means for rotating said frame whereby the bottle carrying members are propelled successively around said track.

2. In a bottle washing machine, the combination of a plurality of bottle carrying members, a stationary frame having a guideway on which the bottle carrying members travel, a rotatively mounted cylindrical propelling frame engaged with each of said bottle carrying members to move the bottlecarrying members along the guideway, and means for intermittently imparting a rotary movement to said propelling frame whereby to propel said members along said guideway.
